Use the database that contains the
data from 20 healthy women volunteers aged 20 to 35
years old in Geneva Switzerland. These women had not
been taking oral contraceptives for at least 3 months
before the start of the study. Daily morning blood
samples were taken on starting on the first day of
their menstrual cycle (determined by the beginning of
their menstrual bleed = menses) and continued to the
first day of their next menstrual bleed.

Six hormones were measured in the
blood samples:

FSH

LH

Prolactin

Oestradiol

Progesterone

Testostrone

UI = International Units
pg = picograms
ng = nanograms

The data was complemented by
ultrasound scans of the volunteers’ ovaries to
determine the stage of the follicles.
